Question

Resolvem-

a) x + 5= 21 b) y - 3= 100 c) x + 17= 10

d) x - 3= 10 e) -3y= 5

Answer 1

A) X + 5 =21
x = 21 - 5
x = 16

B) y - 3 = 100
y = 100 + 3
y = 103

c) x + 17 = 10
x = 10 - 17
x = -7

d) x - 3 = 10
x = 3 + 10
x = 13

e) -3y = 5
3y = -5
y = -5/3

Bons estudos ♡

Answer 2

A)x+5=21
x=21-5
x=16
B)y-3=100
y=100-3
y=97
C)x+17=10
x=10-17
x=-7
D)x-3=10
x=10+3
x=13
E)-3y=5
y=5+3
y=8
