10. y=3x-34 ; y=2x-5
3x-34=2x-5
x-34=-5
y=2x-5
x=29
y=2x-5 = 2(29) -5= 53
Answer: x= 29 ; y=53
14. y=-3x+4 ; -6x-2y=-8
−6x−2(−3x+4)=−8
Simplify both sides of the equation.
−6x−2(−3x+4)=−8
−6x+(−2)(−3x)+(−2)(4)=−8(Distribute)
−6x+6x+−8=−8
(−6x+6x)+(−8)=−8(Combine Like Terms)
−8=−8
−8=−8
Step 2: Add 8 to both sides.
−8+8=−8+8
0=0
Answer: All real numbers are solutions.
