Question

y=3x-4
y= 10x - 7
Round to the nearest hundredth.

Answer 1

Answer: See below

Explanation:

y = 3x - 4
y = 10x - 7

Solve by substitution:

3x - 4 = 10x - 7
3x - 10x = -7 + 4
-7x = -3
x = -3/-7
x = 3/7
x = 0.42

Substitute x value to find y:

y = 10(0.42) - 7
y = 4.2 - 7
y = -2.8

Therefore, x = 0.42 and y = -2.8
