Solve systems by using substitution
y=x+6
y=2x

2x = x + 6

x = 6

Sub x=6 into y=2x

y = 2x

y = 2 * 6

y = 12

therefore y = 12 and x = 6

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!
