Solution for the system of linear equations is (4, - 3)
<u>Step-by-step explanation:</u>
Step 1:
Given system of equations
x - 3y = 13 -------- (1)
2x + 4y = - 4 ----- (2)
Step 2:
Multiply eq(2) with 2 to make coefficients of x equal.
2x - 6y = 26 ------ (3)
Step 3:
Subtract eq(2) from eq(3)
⇒ - 10y = 30
⇒ y = -3
Step 4:
Find value of x by substituting value of y in eq(1)
⇒ x - 3 × (-3) = 13
⇒ x + 9 = 13
⇒ x = 4
