2(x+4x)+3=11-2+4x
⚠ 2( is read as the product 2*(...): for a power, write 2^(...)‖4x is read as the product 4*x: for a power, write 4^x
Let's solve in ℝ: 2·(x + 4x) + 3 = 11 -2 + 4x
ℹx + 4x = 5x‖11 -2 = 9
2·5x + 3 = 9 + 4x
10x + 3 = 9 + 4x
10x = 6 + 4x
10x -4x = 6
6x = 6
x = 66
▶Solution found: x = 1
