Solve for x<br><br> (picture is included below)

Anna11 [10]

Solve for x:

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

Slope of M(-2, 3), N(7 -4)

Mila [183]

Answer:

$-\frac{7}{9}$

Step-by-step explanation:

We find slope by; change in y ÷ change in x,

Change in y = -4 - 3 = -7

Change in x = 7 - - 2 = 9

Slope of line MN = -7 ÷ 9 = $-\frac{7}{9}$
