Mathematics
1 answer:
Tju [1.3M]3 years ago
4 0

Answer:

(3,4)

Step-by-step explanation:

first you're going to solve the equation -2x

your equation should now be: \left \{ {{-2x+3y\\=6} \atop {-2x=2-2y}} \right.

next you're going to substitute the given value of -2x into the equation -2x+3y=6

so your equation should now be: 2-2y+3y=6

next you're going to solve the equation for y

equation should now be: y=4

than you're going to substitute the given value of y into the equation -2x=2-2×4

then you're going to solve the equation for x

your equation should now be: x=3

then the possible solution of the system is the order pair: (x,y)=(3,4)

Y = x + 1.75...so we sub in x + 1.75 for y in the other equation

4x - 2y = 4
4x - 2(x + 1.75) = 4....distribute thru the parenthesis
4x - 2x - 3.5 = 4....add 3.5 to both sides
4x - 2x = 4 + 3.5...simplify
2x = 7.5....divide both sides by 2
x = 7.5 / 2
x = 3.75

now we sub in 3.75 for x in either of the original equations to find y.

y = x + 1.75
y = 3.75 + 1.75
y = 5.5

so ur solution is : (3.75,5.5) <==
