Answer 1

$\huge\mathfrak\red{Answer}$

1. y + 3 = 10

y = 10 - 3

y = 7

2. 5t - 3 = 3t - 5

5t -3t = -5 + 3

2t = -2

t = -1

3. 8x + 4 = 3 (x - 1) + 7

8x + 4 = 3x - 3 + 7

8x - 3x = -4 -3 + 7

5x = 0

x = 0

4. 2x /3 + 1 = 7x /15 + 3

10x/15 - 7x/15 = 3 - 1

3x/15 = 2

3x = 30

x = 10

5. 2y + 5/3 = 26/3 - y

2y + y = 26/3 - 5/3

3y = 21/3 = 7

y = 7/3

6. 4z + 3 = 6 + 2z

4z - 2z = 6 - 3

2z = 3

z = 3/2

7. (m- 29) + m + (m + 26) = 135

m - 29 + m + m + 26 = 135

3m = 135 + 3

m = 138/3 = 46

8. 300 = (160 - 4m) + 6m + 5m

300 = 160 - 4m + 6m + 5m

300 - 160 = 7m

140 = 7m

20 = m

9. 5a + 21 = 2a + 42

5a - 2a = 42 - 21

3a = 21

a = 7

10. (x - 5) /3 = (x - 3) /5

5(x - 5) = 3(x - 3)

5x - 25 = 3x - 9

5x - 3x = -9 + 25

2x = 16

x = 8

Hope it helps youu!! ❤

Answer 2

1. y = 10-3 =7

2. 5t-3t = -5+3

2t = -2

t = -1

3. 8x+4 = 3x-3+7

8x-3x = 4-4 = 0

5x= 0

x = 0

4. 10x +15 = 7x + 45 (multiply by 15 on both side)

10x-7x = 45-15

3x = 30

x = 10

6. 4z-2z = 6-3

2z = 3

z = 3/2

7. m-29+m+m+26 = 135

3m -3 = 135

3m = 138

m = 46

8. 300 = 160-4m+6m+5m

300-160 = 7m

140/7 = m

20 = m

9. 5a-2a = 42-21

3a = 21

a = 7

10. 5(x-5) = 3(x-3)

5x-25 = 3x-9

2x = 16

x= 8

11. 6x+42-16x = 17- 15x

-10x+15x = 17-42

5x = -25

x = -5
