- 10
- 30
- -6
- 4
2.
Solve for [math]x[/math].
[math]7x + 5 = -x + 41[/math]
[math]7x + 5 = -x + 41[/math]
- 53
- 8
- 4.5
- 5
3.
Solve.
[math]-12 + 6(2x - 2) = 0[/math]
[math]-12 + 6(2x - 2) = 0[/math]
- x = 4
- x = 1
- x = -2
- x = 2
4.
What is the solution to the following equation?
[math]2(3x + 5) - 2x + 2 = 0[/math]
[math]2(3x + 5) - 2x + 2 = 0[/math]
- x = -3
- x = -2
- x = -1
- x = 2
5.
Solve:
[math]8x - 4(x + 2) = 12 (x + 1) -14[/math]
[math]8x - 4(x + 2) = 12 (x + 1) -14[/math]
- [math]x = 1/4[/math]
- [math]x = -3/4[/math]
- [math]x = 2/3[/math]
- [math]x = 1/5[/math]
6.
Solve.
[math]-4(r+5)-2=2(9+2r)[/math]
[math]-4(r+5)-2=2(9+2r)[/math]
- r = -5
- r = -2.5
- r = -2
- r = -1.5
- r = -1
7.
What is the solution of [math]-8x-5+3x=7+4x-9[/math]?
- [math]x=-3[/math]
- [math]x=-1/3[/math]
- [math]x=1/3[/math]
- [math]x=3[/math]
8.
What is the solution to [math]2n-3(4n+5)=-6(n-3)-1[/math]?
- [math]n = -8[/math]
- [math]n=-6[/math]
- [math]n=-1/2[/math]
- [math]n=4[/math]
9.
Find the value of [math]x[/math] if [math]6(2 - x) + 4x = -5(x + 3).[/math]
- -9/5
- -7/3
- -27/7
- -9
10.
Solve for [math]a[/math].
[math]20a + 14 + 11a = -47[/math]
[math]20a + 14 + 11a = -47[/math]
- [math]61[/math]
- [math]61/31[/math]
- [math]-61/31[/math]
- [math]-61[/math]
