Answer:
x=15 and y=49
Step-by-step explanation:
y+16=5x-10
and (y+16) + (8x-5)=180
so y=5x-26 and then
plug in for y so 5x-26+16+8x-5=180
that means x=15
plug in for x
y+16= 5(15)-10
that means y=49
thanks for the brainliest!
Answer:
x = 2 and y = 5
Step-by-step explanation:
Given the simultaneous linear equations
y = 2x + 1 and x + y = 7
We are to find the value of x and y;
Substitute 1 into 2
From 2;
x+y = 7
x+2x+1 = 7
3x+1 = 7
3x = 7-1
3x = 6
x = 6/3
x = 2
Recall that y = 2x+1
y = 2(2) + 1
y = 4+1
y = 5
Hence the solution from the graph will be the point where the line cuts the x axis and this will be at x = 2 and y = 5
Answer:
y = 2x + 3
Step-by-step explanation:
3 is the constant
2 is the rate at which recieves
So, y = 2x + 3
Answer:
u= 2.5
Step-by-step explanation:
Using BIDMAS
Step 1: Expand the bracket
9(u-2) + 1.5u=8.25
9u-18+1.5u=8.25
Step 2: collect like terms
9u+1.5u=8.25+18
10.5u=26.25
Step 3: Divide both sides by 10.5 to get u
u= 
= 2.5
I believe the answer is c im am stuck on the same problem do you know the answer?<span />
