Question

c)35+16+a=200-48
d)b-(21+2*16)=308:4

Answer 1

c) 35+16+a=200-48
51+a=152
a=152-51
a=101

d) b-(21+2*16)=308:4
b-(21+32)=77
b=77-53
b=24

Answer 2

$35 16 + a = 200 - 48 \\ \\ a = 200 - 48 - 35 - 16 \\ \\ a = 101 \\ \\ b - (21 + 2 \times 16) = 308 \div 4 \\ \\ b - (21 + 32) = 77 \\ \\ b - 53 = 77 \\ \\b = 77 + 53 \\ \\ b = 130$
