Answer:

x = 0.7

y = 4.2

Coordinate form : (0.7, 4.2)

Step-by-step explanation:

Solve:

Plug in in 6x for y in 4x + y = 7

  • 4x + y = 7
  • 4x + 6x = 7
  • 10x = 7
  • x = 0.7

Plug in 0.7 for x in y = 6x

  • y = 6x
  • y = 6(0.7)
  • y = 4.2

x = 0.7
y = 4.2

Coordinate form : (0.7, 4.2)

Answer:

x = 7/10 (fraction)

Step-by-step explanation:

Given that y = 6x, we can substitute it for y

That makes your equation:

4x + 6x = 7

Now, all we need to do is solve for x:

Step 1: Add similar elements:

4x+6x=10x, which gives you 10x=7

Divide next:

10x/10=7/10 (10/10 = 0 and 7/10 = 7/10)

x= 7/10
