The value of the unknown variable "x" given that -6x + 3= 45 is -7
Equations are expressions separated by an equal sign. They can contain one or more variables.
The equation given in question is a linear equation containing one unknown variable "x".
The equation is expressed as -6x + 3 = 45
To get the value of x, we will follow the steps below:
Step 1: Subtract 3 from both sides of the equation
-6x + 3 - 3 = 45 - 3
-6x = 42
Step 2: Divide both sides of the expression by -6
-6x/-6 =42/-6
x = -7
This shows that the value of the unknown variable "x" is -7.

Answer:
(-4,-2)
Step-by-step explanation:
first u should chose a variable to eliminate and i choose Y
y=5/2x+8-y=-1/4x-3
get a common denominator
5/2= 10/4
-1/4=-1/4
the equation i will change a little because we are subtracting
10/4x+8+1/4x+3
11/4x+11
solve for the remaining variable which is X
subtract 11 on both sides
0-11=11/4x+11-11
-11=11/4x
multiply both sides by 4/11
-11 times 4/11= 11/4x times 4/11
x=-4
then substitute the variable in one of the equations and i choose y=5/2x+8
5/2(-4)+8= y
-20/2+8= y
-10+8=y
y=-2
