Answer: See explanation
Step-by-step explanation:
7.) 2 (x - 1) = 45
2x - 2 = 45
Add 2 to both sides
2x = 47
<em>x = 23.5</em>
<em />
8.) 5x - 2 = 2 (4)
5x - 2 = 8
Add 2 to both sides
5x = 10
Divide both sides by 5
<em>x = 2</em>
<em />
9.) x = 2 (30)
<em>x = 60</em>
<em />
10.) 3x - 6 = 2 (x)
3x - 6 = 2x
Add 6 to both sides
3x = 2x + 6
Subtract 2x from both sides
3x - 2x = 6
<em>x = 6</em>
2x + 1
Substitute x for 6
2 (6) + 1
12 + 1 = 13
2y = 13
Divide both sides by 2
<em>y = 6.5</em>
<em />
