B, T=2L+7, Toby is 2*the age of liv plus 7 years
SIMPLIFIED: 2/7 (10/35)
Step-by-step explanation:
10 people out of 35 made an A. To simplify, you would have 2/7. You would have to divide both numbers by 5.
In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:
y - 4x = 9
-x + 4 = y
Add x to both sides of the second equation:
y + x = 4
y - 4x = 9
This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:
5x = -5
x = -1
Use x to solve for y:
y + (-1) = 4
y = 5
So, x = -1 and y = 5.
Answer:
x = 7 and y = 0
Step-by-step explanation:
We can either solve by substitution method or by elimination method or both method . We will solve by both the elimination and substitution method.
X+y=7 ---------------------------------------------------(1)
-x+y=-7 -------------------------------------------------(2)
Subtract equation (2) from equation(1)
2x = 14
Divide both-side of the equation by 2
2x/2 = 14/2
x = 7
Substitute x = 7 into equation (1)
x+y=7
7 + y = 7
Subtract 7 from both-side of the equation
7-7 + y = 7-7
y = 0
x = 7 and y =0
