# O solve this system of equations by addition, what could you multiply each equation by to cancel out the x-variable? A: 5x - 2y = 10 B: 4x + 3y = 7

##### 1 Answer

#### Answer:

Multiply

Multiply

#### Explanation:

In order to cancel out the

For

#4(5x-2y=10)#

#color(darkorange)("Equation"color(white)(i)1)# :#20x-8y=40#

Similarly, for

#5(4x+3y=7)#

#color(darkorange)("Equation"color(white)(i)2# :#20x+15y=35#

Since elimination works by subtracting one equation from the other, if you try subtracting equation

#color(white)(Xx)20x-8y=40#

#(-(20x+15y=35))/(color(blue)(0x)-23y=5)#
