I need help with the steps. The answer is (5,2)
Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

y+3+y=7\\2y+3=7\\2y=4\\y=2

Next, now that we have the value of y, substitute it into either equation to solve for x:

x+2=7\\x=5\\\\x=2+3\\x=5

<u>And this is how you get your final answer (5,2).</u>

2q+10=7q how do i break this down to get the answer
krok68 [10]
So subtract 2q from both sides.
This will cancel out the 2q on the left.
So the equation right now should be 10=5q.
Now divide each side by 5.
10/5=2
2=q.
That's the answer! Hope this helped!!

X+3/2 + (x-1) = 4/5 ​
tester [92]

Answer:

x = \frac{3}{20}

Step-by-step explanation:

Given

x + \frac{3}{2} + (x - 1) = \frac{4}{5}

Multiply through by 10 ( the LCM of 2 and 5 ) to clear the fractions

10x + 15 + 10(x - 1) = 8

10x + 15 + 10x - 10 = 8

20x + 5 = 8 ( subtract 5 from both sides )

20x = 3 ( divide both sides by 20 )

x = \frac{3}{20}
