<span>Simplifying 2(10 + -13x) = -34x + 60
(10 * 2 + -13x * 2) = -34x + 60
(20 + -26x) = -34x + 60
 Reorder the terms: 20 + -26x = 60 + -34x
 Solving 20 + -26x = 60 + -34x
 Solving for variable 'x'.
 Move all terms containing x to the left, all other terms to the right.
 Add '34x' to each side of the equation. 20 + -26x + 34x = 60 + -34x + 34x
 Combine like terms: -26x + 34x = 8x 20 + 8x = 60 + -34x + 34x
 Combine like terms: -34x + 34x = 0 20 + 8x = 60 + 0 20 + 8x = 60
Add '-20' to each side of the equation. 20 + -20 + 8x = 60 + -20
 Combine like terms: 20 + -20 = 0 0 + 8x = 60 + -20 8x = 60 + -20
 Combine like terms: 60 + -20 = 40 8x = 40
 Divide each side by '8'. x = 5
 Simplifying x = 5</span>

SHOW STEPS!! <br><br> 4. <br> x + 4y -- 67 = -1<br> 2x - y + 2z = -7<br> -x + 2y -- 43 = 5
mafiozo [28]
1.x+4y- - 67 =-1
x+4y+67=-1
x+4y=-1-67
X+4y=-68

2.2x-y+2z=-7
2x=-7+y-2z
x=-7/2+1/2y-z
x=-7/2+1/2y-z, y€R, z€R

Warning: I don’t have the € and R

3.-x+2y- -43=5
-x+2y+43=5
-x+2y=5-43
-x+2y=-38
x-2y=38

Hope this helps!
