Question

please solve -4x -5y=-17 3x+2y=4

Answer 1

Step-by-step explanation:

you should find the value of Y

Answer 2

Given:-

➜-4x-5y=-17-(1)

➜3x+2y=4-(2)

$\rule{200}{1}$

To Find:-

✪The Value of x&y?

$\rule{200}{1}$

AnsWer:-

☞x=-2

☞y=5

$\rule{200}{1}$

▼Multiply (1) by -3▼

↝12x+15y=51-(3)

▼Multiply (2) by 4▼

↝12x+8y=16-(4)

★Subtract (3)&(4)★

•12x+15y=51

•12x+8y=16

✪Signs Changed✪

↝7y=35

↝y=$\frac{\cancel{35}}{\cancel{7}}$

☞y=5

♦Using y in (2)♦

↝3x+2×5=4

↝3x+10=4

↝3x=4-10

↝3x=-6

↝x=$\frac{\cancel{-6}}{\cancel{3}}$

☞x=-2

$\rule{200}{2}$
