Question

1. x+8=15
2. x-5=17
3. y+0.4=1.6
4. -2.7+a=-6.4
5. x+9=-5
6. y-7=-3
7. y-2.4=3.6
ada yg ngerti cara kerjainnya tolongg

Answer 1

1. x + 8 = 15
x = 15 - 8
x = 7
2. x - 5 = 17
x = 17 + 5
x = 22
3. y + 0 × 4 = 1 × 6
y + 0 = 6
y = 6
4. - 2 × 7 + a = 6 × 4
- 14 + a = - 24
a = - 24 + 14
a = - 10
5. x + 9 = - 5
x = - 5 - 9
x = - 14
6. y - 7 = - 3
y = - 3 + 7
y = 4
7. y - 2 × 4 = 3 × 6
y - 8 = 18
y = 18 + 8
y = 26

Answer 2

1.x=15-8
X=7
2.x=17+5
X=22
3.y=1.6-0.4
Y=1.2
4.a=-6.4+2.7
A=-3.7
5.x=-5-9
X=-14
6.Y=-3+7
Y=4
7.y=3.6+2.4
Y=6.0
Sorry klo kurang teliti:v
