Question

Solve the following equations without transposing and check your result:
x+5=9
y-12=-5
3x+ 4=19
9z=81
3x+8=5x+2
5y+10=4y-10

Answer 1

Answer:

i)x=4

ii)y=7

iii)x=5

iv)z=9

v)x=3

vi)y=-20

Step-by-step explanation:

i)4+5=9

ii)7-12=-5

iii)3(5)+4=15+4=19

iv) 9(9)=81

v) 3(3)8=5(3)+2

9+8=15+2

17=17

vi) 5(20)+10=4(-20)-10

-100+10=-80-10

-90=-90
