Solve each of the following systems of equations using the s

Solve each of the following systems of equations using the substitution method: SYSTEM OF EQUATIONS: {x = 5y - 12 3x + 8y = 10 solution: SYSTEM OF EQUATIONS {12x + Y = 98 y = 4x - 30 solution: SYSTEM OF EQUATIONS: {4x^2 + y^2 = 64 y middot 2x + .8 solution: SYSTEM OF EQUATIONS: 2x^2 + xy = 18 4x^2 + xy = 26 solution:

Solution

a. x=5y-12

3x+8y=10

substituting the value of x in second equation

3(5y-12)+ 8y=10

15y-36+8y=10

23y=46

y=2

And x= 5y-12=5(2)-12=-2
