Both of them are on the top of the evidence pyramid.
Systematic Review (SR): is a review addressing a specific research question (on treatment, diagnosis, prognosis, and etiology) using the explicit methodology of collecting, selecting, and appraising studies and whenever appropriate synthesizing their results quantitatively.
Simply listing all researches outcomes on a specific topic in a very systematic way under the background of particular eligibility criteria.
While the meta-analysis is the Statistical (quantitative) combination of results from two or more studies addressing the same research question.
Simply, is joining all results of the different studies of the same topic in one number.
e.g. odds ratio of different studies on particular topics combined statistically together.
SR is more of a qualitative assessment of all studies of a similar topic, while a meta-analysis is more of a quantitative combined assessment.

A systematic review is a high-level overview of primary research on a particular research question that systematically identifies, selects, evaluates, and synthesizes all high quality research evidence relevant to that question in order to answer it.
Meta-analysis is a Systematic reviews often use statistical techniques to combine data from the examined individual research studies, and use the pooled data to come to new statistical conclusions.
