To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of

babymother [125]

Answer:

The value of y is $y=\frac{42}{17}$

Step-by-step explanation:

we have

$4x+3y=6$ -----> equation A

$18x+5y=6$ -----> equation B

To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides

I choice

Multiply the equation A by -18/4 both sides

$(-18/4)[4x+3y]=6*(-18/4)$

$-18x-13.5y=-27$ ------> equation C

Adds equation B and equation C

$18x+5y=6\\-18x-13.5y=-27\\-------\\5y-13.5y=6-27\\-8.5y=-21\\\\ y=\frac{42}{17}$

Alex_Xolod [135]

Answer:

Solving for x. Want to solve for y instead?

1 Factor out the common term 44.

4(7x+8y)=884(7x+8y)=88

2 Divide both sides by 44.

7x+8y=\frac{88}{4}7x+8y=

3 Simplify \frac{88}{4}

to 2222.

7x+8y=227x+8y=22

$\cfrac{7-4i}{2+i}\\\\ = \cfrac{(7-4i)(2-i)}{(2+i)(2-i)} \\\\ =\cfrac{14-7i-8i-4}{4+1} \\\\= \cfrac{10-15i}{5} \\\\= \cfrac{5(2-3i)}{5} \\\\=2-3i$
