j) 3x -2 = 4x +9
k) 5x -3 + x = 2x +9
l) 17x -7x = x +18
m) x+x -4 = 17 -2x +1
n) x+2x +3 - 5x = 4x -9​

Answer 1

Explicação passo-a-passo:

i) 16×-12×=3+1

4×=4

×=4/4

×=1

j) 3×-4×=9+2

-1×=11

×=11/1

×=11

k) 5×+×-2×=9+3

6×-2×=12

4×=12

×=12/4

×=3

l) 17×-7×-×=18

10×-×=18

9×=18

×=18/9

×=2

m) ×+×+2×=1+17+4

4×=22

×=22/4

n) ×+2×-5×-4×=-9-3

3×-5×-4×=-12

-2×-4×=-12

-6×=12

×=12/-6

×=-2
