Question

Solve the given system by adding or subtracting equations in steps

x + 4y = 11
x - 6y = 11

Answer 1

`x = 11\\\\y = 0`

Explanation:

Given equations are

x + 4y = 11 ....... [1]

x - 6y = 11 ....... [2]

[1] - [2]

`x-6y& =11\\-\\\underline{x+4y=11}\\\\-10y &= 0\\\\y = 0\\\\`

Substitute y = 0 in equation [1]
x + 4y = 11

x + 4(0) = 11

x = 11
