Answer:
51+(4x+7)=90
4x+58=90
-58 -58
4x=32
4x/4=32/4
x=8
Step-by-step explanation:
Answer:
Step-by-step explanation:
you just need to add both equations
you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
Answer:
I know that the equation has infinity many solution
12x+8=12x+8
That would be the final answer
It's multiplication. Simply multiply 0.3 by 4. How multiplying dedcimals works is that we forgett the decimal until later. So, first we have 3 times 4. What's that? 12. And how many numbers did we have after the decimal? One. So, we hop over one decimal space to receave the answer 1.2. I hope I helped!!!
