The value of x from the given set of equations is 0.30
Given the simultaneous equation
5x-6y=2.7
10x+7y=1.6
Using the elimination method;
Multiply equation 1 by 2 and equation 2 by 1 to have:
10x-12y=5.4
10x+7y=1.6
Subtract
-12y - 7y = 5.4 - 1.6
-19y = 3.8
y = -3.8/19
y = -0.2
Substitute y = -0.2 into equation 1 as shown:
5x - 6(-0.2) = 2.7
5x + 1.2 = 2.7
5x = 2.7 - 1.2
5x = 1.5
x = 1.5/5
x = 0.3
Hence the value of x from the given set of equations is 0.3
