So you basically plug in the x value beside the 5 so if your on number 3 the answer would be 5(3) which is 15
5a)
2x + 94 = 7x + 49 (vertical angles are equal)
2x - 7x = -94 + 49
-5x = -45
x = 9
Answer
9
5b)
4y + 7x + 49 = 180 (supplementary angles, sum = 180)
4y + 7(9) + 49 = 180
4y + 112 = 180
4y = 68
y = 17
Answer
17
6)
x = 6x - 290 (vertical angles are equal)
-5x = -290
x = 58
Answer
58
solve for y by subtracting 3x from each side
-4y = -3x+8
divide by -4
y = 3/4 x -2
