This study aims at determining the effect of spatial intelligence and mathematical logic intelligence on students' mathematics achievement in material systems of two variable linear equations. This ex post facto research was conducted at class VIII of SMP 5 Kendari, Southeast Sulawesi, Indonesia. The sampling technique was done by a simple random technique. Of the 10 classes, VIII available, one class was randomly selected as a sample, namely class VIIIG. Data was analysed using simple linear regression to determine the effect of each variable on mathematics achievement and multiple regression to determine the joint effect of spatial intelligence and mathematical logic intelligence on student mathematics achievement. The research findings indicated that there was a significant effect of spatial intelligence and mathematical logic intelligence on students' mathematics achievement, both partially and jointly, with the regression equation model Ŷ = 23, 755 + 0.527X1, with r2 = 0.654, Ŷ = 43,926 + 0.291X2 with r2 = 0.684, and Ŷ = 29.107 + 0.295X1 + 0.181X2 with R2 = 0.791. © 2019 Primrose Hall Publishing Group.
