Question

360-2*a=350
448-32:a=440
672-a*9=600
598-a:8=592

Answer 1

360 - 2 x a = 350
2 x a = 360 - 350
2 x a = 10
a = 10 : 2
a = 5

448 - 32 : a = 440
32 : a = 448 - 440
32 : a = 8
a = 32 : 8
a = 4

672 - a x 9 = 600
a x 9 = 672 = 600
a x 9 = 72
a = 72 : 9
a = 8

598 - a : 8 = 592
a : 8 = 598 - 592
a : 8 = 6
a = 8 x 6
a = 48
