Question

Solve the following equations
3+x =8
2a - 7 = 3
5y =30
3x - 7 = x+5
2x/3=4
3t - 6 =2t -4
​

Answer 1

Step-by-step explanation:

1) 3+x=8

x=8-3

x=5

2) 2a-7=3

2a=3+7

2a=10

a=10/2

a=5

3) 5y=30

y=30/5

y=6

4) 3x-7=x+5

3x-x=5+7

2x=12

x=12/2

x=6

5) 2x/3=4

2x=4×3

2x=12

x=12/2

x=6

6) 3t-6=2t-4

3t-2t=6-4

t=2

Answer 2

$3 + x = 8 \\ x = 8 - 3 \\ x = 4$

________________

$2a - 7 = 3 \\ 2a = 3 + 7 \\2 a = 10 \\ a = \frac{10}{2} \\ a = 5$

_________________

$5y = 30 \\ y = \frac{30}{5} \\ y = 6$

_________________

$3x - 7 = x + 5 \\ 3x - x = 5 + 7 \\ 2x = 12 \\ x = \frac{12}{2} \\ x = 6$

__________________

$\frac{2x}{3} = 4 \\ 2x = 12 \\ x = \frac{12}{2 } \\ x = 6$

_________________

$3t - 6 =2t - 4 \\ 3t - 2t = - 4 + 6 \\ t = 2$
